UK Biodiversity Indicators 2021. Indicator C8 – Mammals of the wider countryside (bats) 2021
These documents support state indicator C8 – Mammals of the wider countryside (bats). The documents include a datasheet and technical background document.
This indicator shows changes in the relative abundance of 11 of the UK’s 17 breeding bat species, based on data from transect surveys, roost counts and counts at hibernation sites. Whilst 11 species are included there are only 10 trends, as an aggregate trend is used for the whiskered bat (Myotis mystacinus) and Brandt’s bat (Myotis brandtii); these two species are difficult to distinguish between in the field. Bat species make up a third of the UK’s mammal fauna and occur in most lowland habitats across the UK.

The UK Biodiversity Indicators were first published in 2007. They were created to provide a measure for reporting on the UK’s progress towards meeting international biodiversity goals and targets. The indicators were comprehensively reviewed during 2011 and 2012 to ensure they continued to be based on the most robust and reliable available data, and remained relevant to the new international goals and targets developed in 2010 and 2011.
